Good question. I think there's interest in subbing the movie, but I don't know how feasible it is right now or if there are any actual plans to do so. Running two 24-episode series, working on an OVA, and most likely picking up Zero no Tsukaima F in January leaves little time to work on a movie =[

Then again, I don't really follow what the SS-Eclipse portion of the group gets up to, so they might surprise us.
